The UNEXMIN partners got together in the island of La Palma in the Canary Islands, Spain, to discuss and better prepare the last year of the UNEXMIN project, that will officially end on the 31st October. The two-day meeting (10 and 11 of January) aimed at providing a place to discuss the present and future development of the project. The field trials and the production of the remaining two UX-1 robots were at the core of the agenda.

The above-mentioned points were largely introduced and discussed during the first day. The UNEXMIN project already underwent through two field trials (Kaatiala and Idrija) and results from the surveying of these mines is currently in development. The experience gained on both trials will allow the team to properly prepare for the surveys on the Urgeiriça (Portugal) and Ecton (UK) mines, where two and three robots will be used, respectivelly.

The production and assembly schedule of the next two UX-1 robots was also outlined in order to avoid any delays, that might hinder the project development. This was agreed by all partners that are involved in the construction of the robotic platform and work will follow inline with planned.

During the second day, and with the main issues to be discussed out of the way, the UNEXMIN partners had a more relaxing meeting. The future of UNEXMIN was discussed (next steps, what about the future, etc) and a mindmapping exercise, that will help to shape the future of UNEXMIN, was organised.

Now it is time to continue working in order to reach the UNEXMIN project’s objectives!

The first UNEXMIN field trials finally started last week (11th to the 15th June). And on these five days a lot happened, with much more to come this week.

On the first day, the UNEXMIN team transported the UX-1 robot – weighting around 100Kg! – and all the necessary equipment to the Kaatiala test site. A base was set up at the shallow part of the lake where the tests are being held to allocate the UNEXMIN team and create its working station.

The next two days served as the last dry tests for the robot, as a preparation for the first official UX-1 swim that finally happened on the 14th. All the necessary sub-systems for navigation and motion (e.g. ballast system, SLS, thrusters, IMU, multibeam-sonar, computer control) were tested on the 14–15th of June in 2 to 5m deep water, and autonomous motion and navigation tests started on the 15th.

During the weekend, the UNEXMIN team moved their base to the deep part of the lake, where the underground tunnels are located. It is in this area that the UX-1 robot will perform its autonomous operations during this week.

Besides the testing, the UNEXMIN team have also been busy with a growing interest from the media, translated in some interviews. One Finnish national TV and four newspapers, and one international TV (Euronews) were present at the site to learn more and share the UNEXMIN project to their readers and viewers!

UNEXMIN partners met in the beautiful city of Porto during the 28th and 29th of July.

The reason for this reunion was a UNEXMIN follow-up meeting on the project where every currently running Work Package (a block of the work breakdown structure) coordinator presented a review of the work done until now, and a planning of respective future developments.

There were also many relevant discussions on topics related to UNEXMIN’s overall advancement, such as project organisation and the development of UX-1, the multi-robotic platform.

The UNEXMIN team discussing UX-1 developments

One of the main points from this meeting was the debate concerning the first prototype’s construction and development. The questions raised about the project’s progress will have a final and determinant answer when UNEXMIN partners meet in Tampere in September, where they will take part in a one-week-work agenda totally devoted to clarify the next steps to take regarding UX-1.

UNEXMIN partners also visited the labs of INESCTEC (Instituto de Engenharia de Sistemas e Computadores, Tecnologia e Ciência), one of the partners from the UNEXMIN project consortium, who are specialists in sea robotics, and who have past experience in this field related to UNEXMIN. In the labs the consortium could see and learn how the past and current experience in deep sea robotics from INESCTEC will positively impact the UNEXMIN project and the development of a new technology trend – to have a multi-robotic platform capable of mapping flooded mines that are currently inaccessible.

From the 24th to the 26th of May, UNEXMIN partners held a meeting in Tampere, Finland. The meeting, entitled “End-user requirement specification workshop”, aimed to define and specify the technical features of the autonomous multi-robotic explorer in order to best serve end-users who will enlist UX-1’s services in the future.

Discussions included everything from the robot’s size, weight, shape, its autonomy, navigation, survivability under harsh conditions such as underground mines, to the instruments it will carry for geological data collection and post-processing on its future missions.

During this meeting, six workshops were attended by the consortium members in order to discuss and decide the best solutions for the robot’s developments and construction. These workshops were:

Interactive discussion on one of the workshops

Design requirement and environmental consideration

Navigation and tracking (including vision sensor configuration)

Structural layout and safety/survivability considerations

Structural and subsystems design

Essential means for successful geological data collection

Data processing and post-processing

Every topic of great importance for the project’s development was discussed in these workshops, so everything was covered to ensure things are going in the right direction.

On the last day, the consortium members visited a Sandvik Mining and Construction test mine in which drilling tests and monitoring are performed autonomously, similar to one of the technologies UNEXMIN is adapting and developing during the project lifetime. There was also a tour of the TUT laboratories, where the robot’s hull will be constructed.

One of the many laboratories in TUT – Tampere University of Technology.

This meeting allowed the UNEXMIN group to define a specific strategy for the robot’s developments, taking into account different factors such as end-user requirements, materials and instruments availability and navigation, autonomy and survivability constraints. In the end, it was a productive and enjoyable meeting which will get us closer to the final objective of creating an autonomous multi-robot platform!

UNEXMIN members visiting the Sandvik Mining and Construction test mine

On May 3rd, UNEXMIN consortium members visited the Deep Ecton mine, one of the copper mines located in Ecton Hill, Staffordshire (near Manchester), UK. Deep Ecton will be the last and most technologically challenging test site (from a total of four) for the UX-1 multi-platform robots surveying work.

The Ecton Mine produced predominantly copper with lead and zinc as secondary products, which is uncommon in the related mineral district. Mining at Deep Ecton lasted from the Bronze Age until the 19th century, at which time it was Britain’s deepest mine. Mining below river level ceased during the 1850s, and all production ceased in the 1890s.

With UX-1, the innovative multi-robotic system UNEXMIN partners are developing, we intend to map all tunnels and shafts of Deep Ecton. These flooded and currently inaccessible areas were last seen and mapped during the 19th century, meaning the data has not been updated for more than 150 years!

Now, with UNEXMIN developing autonomous underwater submersibles capable of surveying flooded and deep-mine environments, it will be possible to get actual, precise, new data, which would otherwise be impossible to obtain. We will do this without disturbing the environment at Deep Ecton – it is a heritage Site of Special Scientific Interest – or putting human lives in danger.

In order to solve the technical and technological challenges which might arise from this particularly difficult test site, we have a group of robotic experts and technology developers working hard to find the best approach for the UX-1 robots so they can do their work in the best way possible.

The Ecton Mines are great places to visit for a nice day out while learning and observing its geology, archaeology and beautiful landscapes – it is really worthwhile!

EMET (Ecton Mine Education Trust), one of UNEXMIN’s partners, and the institution in charge of the Ecton Mines, is doing a great job preserving and showing the mines to the team. We hope to go back to Staffordshire soon for UX-1’s pilot-test!
